K&N 33-2438 Air Filter Product Reviews

Great idea not to have to replace again, just wash, oil and replace. I love to save money. Thanks, SGM

I have used K&N filters on every car the last few years and always had great results. Cleaning my own filter instead of replacing them is great. Especially helpful when taking many multi state road trips, using dirt roads and going off road. Cleaning and reusing the filter is great.

After replacing the stock air filter with a K&N brand filter I have not seen any change in performance as advertised. Nor is there any change in gas mileage. Does not work for me.

Perfect fit, noticeable increase in horsepower especially while traveling in the mountains of NC. Just finished first tank of gas following replacement and seeing a 1 1/2 mpg improvement. Did the replacement at the recommendation of the Toyota dealership to improve engine performance without compromising warranty. Will be ordering a filter for my wife's car.

Have always used K&N filters. Extreme value, helps boost performance and usually squeaks out an additional mile or two per gallon on fuel.
